Step-by-step explanation:

f(-1)=-1^2 +1 =2

Answer:

C) 2

Step-by-step explanation:

Hope this helps :)

Step-by-step explanation:

The first step is to move the like terms to same side of equation

3x + 9 = 17x - 11 ➡ 9 + 11 = 17x - 3x

then we add like terms

20 = 14x simplify if needed

10 = 7x and x = 10/7

Answer:

Charlie has 6 and Leo has 4

Step-by-step explanation:

6-1=5 and 4+1= 5

brainliest plsss

Answer:

In the beginning, Leo had 3 cars and Charlie had 3 cars.

In this problem, the statements seem to never be true if applied in the initial value. But if we take the value from the first statement and take it in the second, Leo and Charlie having 3 cars is true.

Step-by-step explanation:

Charlie said to Leo that if you give me one car, then i will have twice as many cars as you have.

[tex](L_{1} - 1) = 2L_{2} = C_{2}[/tex]

From that statement after Leo gives Charlie a car, we'll have something like:

Charlie's                        Leo's

    2                                    1

    4                                    2

    6                                    3

Also, from that statement we can imply that we're not dealing with a great amount of cars, because the next statement won't be true.

Leo said if Charlie gives him a car, they will be equal.

[tex]L_{1}= C_{1} - 1[/tex]

Another thing is that if the second consideration holds true after the first statement. I will considerate that.

So,

In the beginning, Leo had 3 cars and Charlie had 3 cars.

In this problem, the statements seem to never be true if applied in the initial value.

Step-by-step explanation:

The general form of an equation of a circle with center at (a, b) and radius r is given as:

(x - a)² + (y - b)² = r²

There is no images available to help decide which circle is the right choice... But with the knowledge of what a standard circle looks like, we can make the choice.

Answer:

f(x) = 4x² + 48x + 149

Step-by-step explanation:same as the one above me.

The numerical values in the equation for a, b, and c will be 4, 48, and 149, respectively.

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2.

The quadratic function is given below.

f(x) = 4(x + 6)²+ 5

Convert the equation into a standard form. Then we have

f(x) = 4(x + 6)²+ 5

f(x) = 4(x² + 12x + 36)+ 5

f(x) = 4x² + 48x + 144 + 5

f(x) = 4x² + 48x + 149

The numerical values in the equation for a, b, and c will be 4, 48, and 149, respectively.

Answer:

  45 cm

Step-by-step explanation:

2 lines will divide the square in thirds. 2 additional lines will divide those thirds into ninths. Pat's 4 lines total 18 cm.

To divide the square into sixths requires 5 lines. To divide it into 36ths requires 5 additional lines. Hence the total number of lines on the second paper is 10/4 = 5/2 times the total on the first paper.

The total length of lines on the second paper is ...

  (5/2)(18 cm) = 45 cm

Step-by-step explanation:

He will have 3 classes done before starting the fourth class.

3 classes x 45 minutes per class = 135 minutes.

1 hour = 60 minutes

134 minutes = 2 hours and 15 minutes.

Before the fourth class starts he was at school for 2 hours and 15 minutes

Answer:

40

Step-by-step explanation:

If two variable y and x are related to one other

then they can be represented as y = kx.

where k is constant of proportionality

Number of football mums is represented by y

and number of ribbons is  represented by x

Then y = kx

Also, It takes 160 ribbons to make 4 football mums

substituting y with 4 and

substituting x with 160 in y = kx, we have

4 = k*160

=> k = 4/160 = 1/40

Thus, constant of proportionality is 1/40.

But here option given are  40 140 80 14

so ,equation can be represented as

x = ky

substituting y with 4 and

substituting x with 160 in x = ky , we have

160 = k*4

=> k = 160/4 = 40

Thus, for equation x = ky ,  constant of proportionality is 40.

Step-by-step explanation:

This sum (from n = 1 to n =6 of 128(1/2)^n can be found in several ways.  Since there are only a few numbers here to add together, we can just write out the given sum as

128(1/2 + 1/4 + 1/8 + 1/16 + 1/32 + 1/64), or

64         + 32  + 16  + 8 + 4 + 2 + 1, which sums up to 63.

[tex]V = \pi * 5^2(13) +\frac{1}{3}\pi * 5^2 (12)[/tex]

Step-by-step explanation:

Given:

The figure is a combination of a cone and a cylinder

Radius (of both), [tex]r = 5[/tex]

Height of Cylinder, [tex]H_1 = 13[/tex]

Height of Cone, [tex]H_2 = 25 - 13 = 12[/tex]

Required:

Volume  of the figure

Let V represents the volume of the figure;

[tex]V_1[/tex] represents the volume of the cylinder

[tex]V_2[/tex] represents the volume of the cone

So, [tex]V = V_1 + V_2[/tex]

Where [tex]V_1 = \pi r^2H_1[/tex] and [tex]V_2 = \frac{1}{3}\pi r^2 H_2[/tex]

So, V becomes

[tex]V = \pi r^2H_1 + \frac{1}{3}\pi r^2 H_2[/tex]

Factorize the above expression

[tex]V = \pi r^2(H_1 + \frac{1}{3}H_2)[/tex]

Substitute [tex]r = 5[/tex]; [tex]H_1 = 13[/tex];[tex]H_2 = 12[/tex]

[tex]V = \pi * 5^2(13 + \frac{1}{3} * 12)[/tex]

[tex]V = \pi * 5^2(13 + \frac{1}{3} * 12)[/tex]

Open Bracket

[tex]V = \pi * 5^2(13) +\pi * 5^2 \frac{1}{3} (12)[/tex]

Reorder

[tex]V = \pi * 5^2(13) +\frac{1}{3}\pi * 5^2 (12)[/tex]

From the list of options given, option c is correct.

Answer:

Step-by-step explanation:

Answer: x=8 and x=-8

Step-by-step explanation:

To find the solutions of the quadratic equation, you want to factor it and set it equal to 0.

x²-16=0

(x+8)(x-8)=0

x+8=0

x=-8

x-8=0

x=8

Now that we have factored and set the factors equal to 0, we found that the solutions are x=-8 and x=8.

Answer:

[rad] 2.41

Step-by-step explanation:

Since it gave you the point and the angle to find, you simply just have to solve for the inverse of cot. Remember cot is the opposite of tan, so cot is cos/sin. In that case, we plug into the calc (in radians):

cot^-1(-√5/2)

Step-by-step explanation:

Answer:

A 50% increase followed by a 33/1/3% decrease. = ? (1 + 0.5)*(1 - 0.3333333) = 1.5 * 0.666667 = 1. Result is same as original.

A 50% increase followed by a 33 1/3% decrease is a net decrease of 16 2/3%.

Here is the explanation:

A 50% increase means that the value is multiplied by 1.5.

A 33 1/3% decrease means that the value is multiplied by 0.6666666666666666.

So, the net effect of the two changes is:

(1.5 × 0.6666666666666666) = 1 - (1/6) = 0.8333333333333334

This is a decrease of 16 2/3%.

For example, if you start with a value of 100, then a 50% increase followed by a 33 1/3% decrease will result in a final value of 83.33.
